After more than 17 years in the abrasives industry as Director of Product Development, Director of Sales, Director of Training and more, I can say with 100% certainty that I understand your frustration with using grinding wheels, cutting wheels and flap discs! They all look the same, pricing is all over the place, everyone promises their Wheel is the best.or cheapest. What they don t tell you is why the wheel you are using doesn t work. They don t tell you how to increase your productivity by looking at the tool, the application, and the wheel. I will tell you. Having used these products in every type of fab shop, I thought it would be a great idea to incorporate these new QR (Quick Response) barcodes on the label of every product. You ve seen these QR codes in all types of advertising. When scanned with your smart phone, your phone automatically goes to some website or video or anywhere it directs you to. The QR barcodes on our labels link to an instructional high definition video of how to use that exact product. We have four different videos for grinding wheels, thin cutting wheels, chop saw blades and flap discs. It s so good we have a patent pending! 2
Resin Bonded Abrasives ANSI Standard Marking System The following diagrams is an example of the ANSI standard marking system for identifying grinding wheels and other bonded abbrasives. A Primary grain used to make the wheel A = Aluminum xide C = Silicon Carbide Z = Alumina Zirconium SG = Seeded Gel 24 of the abbrasive grain Coarse Medium Fine Very Fine 8 30 70 220 10 36 80 240 12 46 90 280 14 54 100 320 16 60 120 400 20 150 500 24 180 600 Wheel Configurations Bonded abbrasive wheels have different configurations depending upon the tool the wheel is used on and the desired end result. Below are the configurations that a wheel can have: C Type 1 A C B Straight Wheel R Hardness of the bond Soft Medium Hard A N R T Z BF Type of bond used B Resinoid BF Resiniod Reinforced E Shelac O Oxychloride R Rubber RF Rubber Reinforced S Silicate V Vitrified Type 27 A B Depressed Center Wheel Type 29 C A Flexible Wheel 3
Sample of Wheel Label Resin Bonded Abrasives Below is an example of a label that can be found on CORETEMPS wheels. We feel it is important to include as much information as possible on all our labels so the end user has the pertinent information he needs to operate the wheel. All of our labels are baked on the wheels during manufacturing process, so the label remains intact throughout the life of the wheel.

Storage and Handling Storage and Handling All abrasive wheels are breakable and therefore care shall be exercised in handling and storage to prevent damage. The following rules, which are based on experience, should be observed: Handle wheel carefully to prevent dropping or bumping Do not roll wheels (hoop fashion) Use trucks or other suitable conveyances to provide support and protection in transporting all wheels which cannot be carried by hand Suitable racks, bins, drawers or boxes shall be provided to store the various types of wheels used Abrasive wheels should be stored in a dry area not subject to extreme temperature changes since some bonds may be affected by excessive humidity and temperature differentials Racks should be located as near as practical to the grinding location, but never where there is danger of damage from passing trucks, crane handling equipment or excessive vibration Important: The following information about safety should be used only as a guide. All products listed in this catalog shall be used in accordance with safety regulations set by OSHA and by the directive described by the American National Safety Institute B7.1, the Canadian Standard Association Safety Code B-173-5 and by the American Brush Manufacturers Association covering: Speed, Safety Guards, Flanges, Mounting Procedures, General Operating Rules, Handling, Storage, and Inspection of General Machine Conditions. Warning: Avoid inhalation of dust generated by grinding and cutting operations. Exposure to dust may cause respiratory ailments as well as irritation to eyes and skin. In most cases, a greater hazard is the exposure to the dust/fumes from the base material being ground or paint or coatings applied to it. Use approved NIOSH or MSHA respirators, safety glasses or face shields, gloves and protective clothing. Provide adequate ventilation to eliminate dust or to maintain dust levels below the permissible exposure level for nuisance dust as classified by OSHA. Refer to Material Safety Data Sheet for further information. All operators must read and understand safety information thoroughly. Follow Safety Instructions: You must follow all operator and safety instructions, as well as all common safety practices which reduce the likelihood of physical injury. Operate Wheels at Recommended Speeds: It is imperative that abrasive wheels be operated at recommended safe speeds. For safety reasons no abrasive wheel shall be operated at a speed greater than that indicated on the blotter or wheel. 28
Dos and Don ts Do always handle and store wheels in a careful manner. Do visually inspect all wheels before mounting for possible damage. Do make sure operating speed of machine does not exceed speed marked on wheel, its blotter or container. Do check mounting flanges for equal size, relieved as required & correct diameter. Do use mounting blotters as required by ANSI standards. Do be sure work rest is properly adjusted on bench, pedestal and floor stand grinders. Do always use safety guard that covers a minimum of one-half (1/2) the abrasive wheel. Do allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before grinding. Do always wear safety glasses or some type of approved eye protection while grinding or cutting. Do turn off coolant before stopping wheel to avoid creating an out of-balance condition. Do follow common sense safety considerations. Do follow federal, state and local laws and regulations. Don t use a wheel that has been dropped or appears to have been abused. Don t force a wheel onto the machine or alter the size of the mounting hole. If wheel won t fit the machine, get one that will. Don t ever exceed maximum operating speed established for the wheel. Don t use mounting flanges on which the bearing surfaces are not clean, flat and smooth. Don t tighten the mounting nut excessively. Don t grind on the side of conventional, straight or Type 1 wheels. Don t use a wheel on any machine that is not properly designed for the specific application of the wheel. Don t start the machine until the safety guard is properly and securely in place. Don t jam work into the wheel. Don t stand directly in front of a grinding/cutting wheel whenever a machine is in operation. Don t grind or cut material for which the wheel is not designed 29
Safety SAFETY & SPEED CONVERSIONS GRINDING WHEEL SAFETY GUIDE SAFETY INFORMATION This safety information should be used only as a guide for the CoreTemp Abrasives range of products. 1. Check all wheels for cracks or other damage before mounting. 2. Check machine speeds against maximum operating speed of the wheel. 3. Be sure that the wheel bore, threaded or unthreaded, fits machine arbor properly ad that flanges are clean, flat, and of the proper type for the wheel you are mounting. 4. Run the wheel in a protected area at least one minute before grinding. 5. Wheels must be properly guarded. 6. Wear protective safety glasses or a proper face shield. 7. Do not use wheels which have been dropped or otherwise damaged. 8. Do not use excessive pressure when mounting wheels between flanges. Tighten nut sufficiently to hold wheel firmly. 9. Do not use heavy side grinding pressure on any type 1 straight sided wheel. 10. Do not mount more than one wheel on a single arbor. STORAGE RPM / SFPM CONVERSIONS DIE GRINDER DEFINITIONS: SFPM = Surface Speed in Feet per Minute RPM = Revolutions per Minute M/S = Meters per Second CoreTemp Abrasive Wheels should be stacked flat, not on their edges. Store in a dry area. The SFPM for most T27 bonded grinding wheels is approximately 15, 600. Note that this is equal to the European standard of 80 M/S or 13,300 RPM for a 4-1/2" diameter wheel. ANGLE GRINDER CALCULATIONS: to convert RPM to SPFM...SFPM = (RPMxDIA) /3.82 to convert SFPM to RPM...RPM = (SFPM x 3.82) / DIA to convert M/S to SPFM...M/S x 197 to convert SFPM to M/S...SFPM x.005 For more information regarding Safe Operating Speeds. refer to ANSI B.7.1 Table 23 - "Standard maximum speeds in surface feet per minute" and Table 35 - "Conversion Table - Wheel speeds." 30
